Dear S-plus users,
Please forgive this question of mine that is more statistical than S
orientated...
We know that if the dependent variable in multiple regression should be a
unimodal, normal distribution. In the event that the dependent variable is
a bimodal, or multimodal distribution, and a multivariate analysis is
necessary, what strategies would you suggest? Can I still use linear
regression, or do I need to transform the variable (knowingly, and accept
that it will lose information)?
Thanks.
Sincerely,
Lin
